Title: Metal shaping processes
IPC: B21B1/08
Filed: 1975-02-13
Abstract: 1503371 Rolling apparatus INTERNATIONAL HARVEST CO 13 Feb 1975 [28 June 1974] 6148/75 Heading B3M  Apparatus for roll forming a metal workpiece includes an electrode, e.g. a roll, of refractory metal which serves both to reduce the workpiece and to supply an electric heating current to the workpiece. The apparatus is suitable for forming workpieces of, e.g. titanium, beryllium, and alloys of nickel and titanium. Suitable forming electrodes, which may operate at up to 2500 F. may be of molybdenum, tungsten, niobium, tantalum, or their alloys. The forming may take place in an argon or inert atmosphere, and a lubricant of flaked graphite or silver, or tungsten powder in a plastics binder may be used. In one form of apparatus, Fig. 5, which is used to roll I-beams the upper and lower work rolls 92 and 94 serve as electrodes through which an electrical heating current is fed to a workpiece. Guide rolls 126 and 138 which are in sets of three in either side of the workpiece, apply a working pressure, the rolls 138 being biased hydraulically towards the workpiece. The rolls 126 and 138 are mounted in a frame 118 which may float vertically in use. The heating current may be A.C., D.C., or a combination of both (Fig. 8, not shown) and may be controlled by a feedback loop to provide a desired workpiece temperature. The workpiece temperature, which is at its highest immediately adjacent the work rolls, is sensed by an optical pyrometer and compared by a set value. In a similar manner, the rolling load on the workpiece can be maintained constant by the use of a feedback loop incorporating load cells. The workpiece may be force fed towards the roll gap by feeding rolls (which may have serrated surfaces) and may also have a tension applied hydraulically to it on the output side of the apparatus. After rolling the work may be bead blasted or heated to provide stress relief. The work rolls may be provided with replaceable inserts. Several roll stands may be arranged in tandem, each stand having refractory work rolls serving as electrodes. Figs. 10 to 12 show the successive deformation of a round bar 310 into an I-beam, in three stands. The bar is first squeezed by grooved rolls 314 and 316 until it extrudes sideways to a section 312. The section is then rolled in two stages to an I-beam.

Title: Cancer diagnostic agents
IPC: G01N33/574
Filed: 1975-10-15
Abstract: In the process for the preparation of recognins, optionally provided with a carrier, normal or diseased tissue is extracted with a neutral buffer with repeated disintegration of the tissue. By this means, protein fractions are dissolved or solubilised. Extraction is then carried out. The fraction having a pK range of 1 to 4 is separated off from the resulting extract of the dissolved or solubilised proteins. This is achieved by adding the extract of the dissolved or solubilised proteins to a chromatographic column and eluting with increasingly acidic solvents. A product is isolated therefrom having a molecular weight of 3,000 to 25,000. The isolation is carried out by filtering the eluate in order to obtain a fraction which contains recognin. The recognin is separated therefrom by thin-layer gel chromatography. The recognin obtained is optionally mixed with a carrier for the purpose of forming a complex compound. This process enables the preparation of recognins which are used for diagnosis and for control of malignant tissue.

Title: Improvements in injection pumps for internal combustion rams
IPC: F02M59/00
Filed: 1953-03-09
Abstract: 724,962. Direct-acting engine. OYER, G. March 9, 1953, No. 6462/53. Class 7 (2). [Also in Group XXVIII] An internal-combustion ram is provided with a device for injecting fuel into the combustion chamber of the ram by means of and in response to the fall of pressure which occurs in the combustion chamber at exhaust. In Fig. 1 a fuel injection pump for attachment to a ram comprises a pump piston 4 attached to a spring loaded piston 2 actuated by combustion gases in the ram cylinder which are admitted to the space below the piston 2 through a passage 1 communicating with an aperture in the ram cylinder situated at a slightly lower level than the exhaust port. The ram piston moving upwards on the firing stroke first opens the aperture connected to the passage 1 and the high pressure gases force the piston 2 upwards to perform the pump suction stroke. Immediately afterwards the ram piston uncovers the exhaust port and the drop in pressure in the ram cylinder permits the piston 2 to be forced down by the spring 3 to cause the plunger 4 to inject fuel into the ram cylinder through passages 7, 8. The stroke of the pump plunger is limited by fixed stops 9, 10, and a ball valve 16 in a passage 15 in the plunger 4 through which the fuel flows from the pressure space 6 to the injector passages 7, 8, prevents air entering the pressure space from the passages 7, 8. In a modification, Fig. 8, the stroke is regulated by an adjustable stop 25 attached to a spring loaded disc 24 which is adjusted by a cam 27 rotatable by means of a square ferrule 31. In a further modification, Fig. 4, the pump actuating means comprises a differential piston 21 which is forced upwards for the suction stroke when the combustion gases are admitted to chambers 19, 20 on both sides of the piston and is forced downwards by the high pressure gases which are trapped in chamber 20 by a non-return valve 22 when the exhaust produces a drop in pressure in the chamber 19.

Filed: 1963-02-19
Abstract: 984,714. Windscreen wipers. M. TRZEBINSKI. Feb. 19, 1964 [Feb. 19, 1963; Oct. 24, 1963], Nos. 6559/63 and 41942/63. Heading A4F. In a windscreen wiper having an arm for moving a wiper blade to and fro means is provided which can be brought into action when required for moving the arm away from the windscreen to hold the wiper blade clear of the windscreen when the arm is moved in one direction across the windscreen. Said means may comprise a bracket 1 mounted on the wiper arm 2 and engaging a pin 3 and a roller 4, which normally move to and fro behind a semi-circular plate 6. When it is desired to move the wiper blade 7 clear of the windscreen when moving in one direction, e.g. towards the centre of the windscreen, a cam 9 is moved by cable mechanism into the path of the roller 4 and causes the cam 2 to move away from the screen about a pivot 10. At the same time a pin 3 on the bracket 1 opens a spring pressed gate 12 in the plate 6 to pass to the front side of the latter to hold the arm 2 in its outer position until it completes its wiping arc when the pin 3 drops through a gap 13 in the plate 6 to return to the rear of the latter. Instead of being moved by a cable mechanism the cam 9 may be moved hydraulically, or by electromagnetic means, or by mechanism actuated by a cam on the wiper motor shaft. In an alternative embodiment the wiper spindle is displaced axially to move the wiper blade away from the windscreen; and in two further embodiments the roller 4 and pin 5 are replaced by a stud and spring pressed detent, and by a stud and a pawl, respectively. The invention may be applied to a windscreen wiper having two blades moving together in the same direction whereby one blade may move snow towards the centre of the windscreen to be collected by the other blade and carried to the side of the windscreen. It may also be applied to a windscreen wiper of the kind having a blade which travels to and fro across the windscreen.
